Compound control, combined with decentralized control and centralized control

As shown in Fig. 10, an example of the indoor lighting configuration of the lighting control system of the present invention has the priority of decentralized control for each user's individual room, while the public area is controlled centrally. For a personal room, basically the wireless communication module in the luminaire 10 is preferably a Bluetooth 4.0 technology dual mode such as CC2560 or CSR1000, so that if no one is in a personal room, the centralized control only turns off the luminaire 10; in other words, concentrates The control is not responsible for the opening of the lights in the individual room. As long as there is someone in the room, the lighting in the room is determined by the user in the room to turn off or off, but the user in the room will actually inform the centralized controller whether it is in the room or not. The centralized controller periodically scans the state of the luminaire 10 to determine whether to turn off the luminaire 10. Or, the luminaire 10 is to broadcast the latitude and longitude and height of the luminaire 10, as well as the state of its associated external sensor, such as a temperature sensor, a gas sensor, and the like. The position of the illuminance sensor can be directly combined with the luminaire 10, or fixed in the indoor use area, or built in the wristband and identification card, or using the existing illuminance sensor of the mobile communication device, using its wireless communication The ability to pass its sensed value to the light source or to BT4.0/WIFI or to the channel gate as the feedback value of the light source illumination control.

Embodiment 1

As shown in Fig. 11, the indoor lighting configuration example of the lighting control system of the present invention is shown in the first layer. The first layer is directly controlled by the personal mobile phone to the lamp 10 provided in the bedroom, for example, the lamp 10 of the master bedroom, which can be set to a sense of vacancy. The function of the detector, when you sleep, will not automatically open because someone enters or exits. The method is to turn on the light 10 with a mobile phone or a wristband, or use a voice command to turn on the light 10 with a mobile phone or a wristband. For a child's bedroom, it is necessary to maintain sufficient illumination to avoid fear. For the entrance and exit, the place that does not stay can be set as the function of the occupancy sensor. When entering the range, turn on the light; when leaving the range, turn off the light. For places with many windows, such as living room, balcony, and yard, you can set the function of the sun sensor, and adjust the light according to the amount of sunshine and the set illumination. The garage or basement can be set to function as a placeholder sensor. When entering the range, turn the lights on; when leaving the range, turn off the lights.

The lighting control of the bathroom and toilet can avoid the switch of the black light when you use it in the middle of the night. The dimmer can be used to reduce the light in the middle of the night. When you shower, you can continue to wear the bracelet to ensure that the lighting is maintained continuously. Secondly, if you fall in the bathroom, you can judge through the acceleration on the bracelet and send out a distress signal. If you use PIR, you may generate lights when you shower. The light and dark flashes.

Basically, countries have illuminance standards to regulate housing, schools, offices, etc. Corner lighting needs. At the beginning of the system layer, the illuminance of each lamp position standard is set according to the illuminance standard table provided by the country, and then the illuminance required by each person is set, for example, the illuminance required by the elderly is high; the system layer checks at any time, and each person's location is based on his identity. , age, special requirements, provide sufficient illumination for dimming the nearby light source at its location, and automatically dim or turn off the nearby light source for areas where there is no one. This can effectively avoid the problem of not turning off the lights.

In order to prevent the user from having to carry the wristband or the mobile phone or the identification card, the light source cannot be turned on. Therefore, the blue light module of the light can be regarded as a switch that can be reset. Usually not used, purely controlled by wireless. Use it in an emergency.

The advantage of this creation is that it does not require a switch on the wall. For an already built house, the switch on the wall can be retained, but as long as it is kept open, the wiring can be saved and the switch box can be set up for the newly built house. The cost makes the decor more flexible. When the room is modified, the lighting part only needs to be configured with the power cord for the lamp, no need to consider the position of the switch box, because the control of the light is wireless.

The mobile phone or the wristband reports its position to the gate gate GATEWAY at any time (every 10 seconds or when the position changes), for example, working in front of the computer, the position is not changed, there is no need to update the position of the gate gate GATEWAY, the system layer is channel The GATEWAY command is based on the position of each person, and the status of each lamp, the ambient illumination, the illuminance near each person, whether it is sufficient, whether a certain lamp should be lit or dimmed, basically borrowing The BT4.0 SLAVE command for each lamp is required to be turned on or off and dimmed by WIFI/BT4.0.

Embodiment 2

A multifunctional bracelet comprising an accelerometer, a Bluetooth communication module, a microcontroller, and at least two buttons, further combining the bluening of the indoor LED lamp, including at least an indoor positioning activity mode, a positioning control light mode, and a hand press Four modes, remote control mode and emergency mode.

As shown in Fig. 12, the LED lamp operates in the positioning/dimming mode. According to the concept of time sharing, the positioning mode and the dimming mode are each 0.5 second, on the assumption that the speed of walking indoors is about 3600 m/s. , an average of 1m / s, updated in 0.5 seconds, in fact, will only cause a delay or error of 0.5 meters, still within the tolerable range.

The Bluetooth low-power module on the LED operates in slave node mode 201, broadcasts for 0.5 seconds, and the broadcast period can basically take 30ms. The broadcast content is mainly the location of the LED light, such as its latitude and longitude and altitude, and is open to nearby actions. The device scans 203. If the minimum time period for the mobile device to scan the LED light is 100ms, the RSSI can be sampled up to 30 times per second, so 15 RSSIs can be obtained in 0.5 seconds. In fact, the RSSI can be averaged to obtain the low noise RSSI. The position algorithm obtains the latitude and longitude and height of the mobile device.

Next, the Bluetooth low power module on the LED operates in the master node mode 202, or in the dimming mode, scanning the surrounding slave mobile communication device for 0.5 seconds, such as a wristband, the bracelet operating in the slave node mode, It can be directly read by the main node of the LED, and the brightness of the dimming is determined according to the strongest value of the RSSI of the bracelet near the LED lamp. Basically, the frequency of automatic dimming does not need to be too high. In fact, it only needs to be adjusted once in a few seconds, mainly to avoid people's habit of turning off the lights without turning off the lights, or too low lighting or excessive lighting. For dimming changes, it is not constantly adjusted. The RSSI can be divided into several segments, for example, four segments. If the RSSI has no segments, there is no need to adjust the brightness of the light.

Regarding the operation of the LED lamp in the positioning/dimming mode in Fig. 12, the proportion of time division is not fixed, and can be adjusted according to requirements. For example, the positioning mode can be operated continuously for 0.5-1.5 seconds, and the dimming mode is 0.5 second, such a In this way, the mobile phone can continue to effectively complete the positioning, and the dimming can also meet the dimming requirements without delay.

It should be noted that if the LED light reads the RSSI message from the Bluetooth slave node near the wristband, it can be dimmed according to the RSSI. However, if no RSSI message from any Bluetooth slave node is read, it may be There are two situations, one may be that the person wearing the bracelet left, and the other may be that the bracelet is in the master mode, so it cannot be read, so based on this point, in principle, the bracelet switches the master and slave. The period should be different from the period in which the LED lamp switches between master and slave. In addition, in order to avoid switching to the off state when the RSSI is not read, after waiting for one cycle, if the RSSI is still not read, it will switch to the off state. The reason is that the probability of turning off the lights is greatly reduced.

Referring to the description of Fig. 13, the wristband operates in the positioning/dimming mode, according to the concept of time sharing, the positioning mode is 0.5-1.0 seconds and the dimming mode is 1.0 second. The Bluetooth low-power module of the bracelet operates in the master node mode 205, scanning the surrounding LED lights from the node mobile communication device for 0.5-1.0 seconds, obtaining the RSSI of the nearby LED lights, and the latitude and longitude and height of the location, Calculate the latitude and longitude and height of the location of the bracelet. Further, it is possible to continuously store latitude and longitude and altitude data, acceleration data, and determine whether there is no movement or activity for too long. 211, if there is no movement and no activity for too long, issue a warning, suggest to do exercises or change the current activity 212.

Next, the wristband operates in the passive dimming mode 206 to broadcast the latitude and longitude and height of the wristband, the MAC address, and the acceleration value. If the LED light is the master node mode 207, the RSSI value of the wristband can be scanned. Perform dimming work. The router 208 is, for example, BT4.0/WIFI or BT4.0/PLC, and its BT4.0 is a master node for a long time. When scanning the latitude and longitude and height of the bracelet, The MAC address, acceleration value, etc. can be stored in the channel gate or the cloud 209 for recording and judgment, activity record, abnormal condition interpretation, warning, and help and rescue. Remote query and monitoring 210 can also be provided.

As shown in Fig. 14, as an embodiment of the wristband, the slide bar 153 of the two-stage switch selects ON. The main function is to turn on the power of the wristband or connect with the mobile phone, and start to exercise and record, if the red LED light 154 flashes slowly, indicating that there is no power, and it needs to be charged. When the slide bar 153 of the two-stage switch is turned OFF, the power is turned off. The red button 151 is used as an emergency button. If there is an urgent problem or need to ask for help from an elderly person or child at home, an emergency room patient in a hospital, or a hospitalized patient, press this button to pass the nearby BT4.0/ WIFI router, BT4.0/PLC router, or BT4.0/GATEWAY is sent to the cloud to request help. At this time, the LED light 154 will flash rapidly. If the cloud receives the message, the rescuer will send it back. This emergency help signal gives the bracelet a response, at which point the LED light 154 will go out. Helpers, just wait for the arrival of rescuers. In addition to hospitals and home caregivers, this bracelet can be used in health villages, kindergartens, kindergartens, primary schools, etc. It can also be used as identification or identification bracelet for factory employees.

The preset mode of the bracelet is an automatic positioning control light, but can be switched to the remote control mode. The purpose of the remote control mode is to make up for the shortage of the positioning control light, for example, the following situation

First, turn off the lights or dim when sleeping, wake up in the middle of the night to go to the toilet or drink water or take medicine to turn on or brighten, you can use the remote control mode, directly by the mobile device, turn on or brighten by remote control After getting up again, you won't be able to see clearly. People who are nearsighted can also find glasses. After going back to the bed after going to the toilet, they can remotely dim or turn off the lights, which is relatively safe. Especially for the elderly In other words, sometimes you have to wear clothes in the winter, you can see if you go out of bed and walk, you will not fall. Sometimes the bedside lamp may not have a bedside lamp, so the remote control mode is necessary.

Second, when watching TV in the middle of the night, if you don't want to turn on the headlights or too bright, you can remotely control it yourself.

Third, the lighting provided by the positioning control lamp can not meet the special needs.

The yellow button 152 is used as a manual remote control button. The main function is to use the mobile communication device to manually control the nearest LED light and remotely turn it off. For related procedures, please refer to Figure 15. When the LED light enters the dimming and color modulating mode 301, first check whether the light-off signal pressed by the manual light button is true 302, and if so, turn off the light 303, and the LED light stores the The MAC address of the Bluetooth module of the bracelet. Wait for the manual light button to be pressed again. If yes, check whether the MAC address of the bracelet matches the previously stored MAC address 304. If yes, identify the identity, age, and other special demand settings 305 by MAC address. Emotion, illuminance sensor measurement, day/night time. The PWM is output to the LED die 306 based on the recent person distance adjustment of brightness and color.

The manual light button refers to any multi-function wristband that appears near the LED light, including the mobile device with the built-in light control APP, or the signal from the central control light system communication gate.

The interaction between mobile communication devices and LED lights, as well as other related applications, requires the establishment of standard communication protocol rules for the micro-controllers in the LED lights to be followed, as shown in Table 1, for various mobile devices, if Adopt Bluetooth low-power module, its broadcast or write communication specifications, as long as you comply with this communication specification, you can achieve intelligent lighting control.

Implementation of four remote control dimming bracelet

Whether day or night, if you want the most appropriate lighting, the best way is to use the illuminance sensor to provide the current ambient illumination, and provide complementary illumination, the illuminance sensor can be connected to the Bluetooth control panel. Connected, but its sensing position is based on the ability to detect ambient illumination. The illuminance sensor can be placed on the wristband to directly detect whether the illuminance around the wearer is sufficient. If you don't want to illuminate the sensor, it is to distinguish between daytime lighting and nighttime lighting, mainly by day or night through sunrise or sunset time.

The manual button functions like a remote control. As shown in Figure 16, the slider 153 of the two-stage switch selects ON. The main function is to turn on the power of the wristband or connect with the mobile phone, and start motion and record if the red LED The light 154 flashes slowly, indicating that there is no power, and it needs to be charged. When the slide bar 153 of the two-stage switch is turned OFF, the power is turned off. As the wristband of the remote control, its operation mode is the master node, and the LED light is at the slave node, so the wristband can establish a connection and write the dimming function thereto, and the button 155 is used to activate the remote control mode, the button 156 is used to adjust the brightness. The flow chart of the overall dimming and toning mode is as shown in Fig. 17, the LED lamp enters the dimming and toning mode 311, and the LED microcontroller checks whether there is a signal 312 received by the remote control, and if not, enters the positioning control lamp. The mode 318 identifies the identity, age, and other special demand setting values through the MAC address, and refers to the mood, the measured value of the illuminance sensor, and the day/night time period. The PWM is output to the LED die 319 based on the recent person distance adjustment of brightness and color.

If the LED microcontroller checks that there is a signal to receive the remote control, enter the remote control mode 313, check to press the dimmer button? If yes, establish a connection 314, accumulate the number of times the dimming button is pressed, and adjust the brightness of the LED light. Each time it is pressed, the first step is brightened until the brightest, and if it is pressed again, the light is turned off until the darkest. If the signal of the dimming button ends more than 5 seconds 315, the connection 316 is cut. Start checking the cancel signal pressed by the remote control light button, and judge that its MAC address is 317. It is permitted to restore the positioning control light mode. The purpose of judging that its MAC address is consistent is to determine whether another person's mobile device will broadcast the cancellation signal issued by the remote control light button, but its MAC address does not match.
